Unconnected wire and not starting

Dear ASEMASTER6371;
I have been devoting most of my time for my pickup's problem.
I have read thoroughly what the 3 links you mentioned go to, and I understood them, but most of my time was spent about the loose cream wire I mentioned. Actually it is a PIAA LR-7 light harness kit installed with six wires either going to or coming from the kit's connector, and it is not only the loose cream wire that I do not know where it connects to, but there is also an unconnected loose black wire of about the same length as the cream one, but my headlights work.
My last effort was to try to put a jumping wire to the solenoid, but I could not do it and it got late. God willing tomorrow I am going to remove the exhaust manifold, if possible.
If it happens you have something to say, it is welcome.

I have not testes the relay with an attempt to crank the engine. If that is necessary I could get my sister to help me do that.
The starting system relay and its metal pins looked in good condition. I only did some relay checks with my multi-meter, and I guess I have bad news.
There is no continuity between the metal pins 85 and 86 of the relay.
With the ignition switch on the "on" position I did not get any voltage neither between terminals 85 and ground nor between terminal 86 and ground.
With the ignition switch on the "on" position I jumped terminals 87 and 30 with a piece of wire. Nothing notorious happened, (maybe a very very low noise sometimes. Then, with the jumping wire still in place I took out the ignition key and put again got the ignition switch in the "on" position. Again, nothing notorious happened, maybe just the very very weak noise sometimes.
If you have suggestions or advice on what to do next, I am open and willing to continue.

I spent much time and I could not send a picture of the loose wire, but I still have hope.

Do you know if pictures taken with a laptop camera can be inserted into my 2CarPros website replies? I have two pictures of the wire taken with my laptop camera I think since last Sunday. I could get them to a USB stick but I have not been able to insert the pictures to my replies.
Now I am trying to see if it is possible to insert pictures into my replies with my cell phone.

But you do not have to mind this? It is my work.

This time I worried too much and lost my mind with my pickup not starting.
Today I felt like checking a push switch hanging from the steering column that a mechanic installed because the solenoid was not activating the cranking contacts most of the times,
One wire going to the push switch was broken at the switch. I Attached the wire and the motor started right away. No need to connect the cream or white wire.
Thank you for having asked me if I had made checks on the starting relay so I did not proceeded to remove the exhaust manifold that would have been a waste of time. And thank you for having bore with me for almost a week.
If I have another trouble with my pickup I hope we can meet again in the internet.

Hi ASEMASTER 6371,

It happens that my vehicle has been starting and shutting off about 15% of the time for some months. Today, due to persecution from voices that I hear, functionally real, I did not crank the motor more times to start the motor and come back from church but left the pickup there to do something about it.
I just have been putting gasoline additives for cleaning the whole fuel system but this has not solved the problem.
Besides buying a device I do not know its name for helping the battery, in case it helps, I only have the idea of increasing the idle speed a little bit, but I have never done any work on the motor and I do not know how to do that, One thing I know is that when I add the 200 amps from my battery charger the battery, the motor has started but that has been only a few times so far.
When the motor shutting off, waiting six minutes makes the motor start most of the times and if it does not, waiting the six minutes repeatedly makes the motor finally start. I have never left the pickup with discharged battery for the last 10 month's.
So I am willing to start working on this problem if you give me suggestions or advice on what I can try, but I also need to know how to perform any work on the motor.
I hope you have something to say and reply.

Before replacing the battery, I am not sure that the problem would be solved, let's say, for at least a year, and since now the infliced disabling impairment on my mind has been ongoing for more than nine hours, and also because of the 40-year prorated impairment on me, I cannot have the clarity for changing the spark plugs, and so I guess I have to first buy a battery protector and go from there.
And because of not having the clarity for changing the spark plugs, It seems that, before taking the pickup for a tune-up, nothing else can be done. Nevertheless, you are always welcome for a reply.

Extremely bad health news.
My pickup battery reads 12.7 volts and with the engine running initially 14.1 and then more. I am not arguing, I am open to why a new battery is better and worth trying.

Hi,
Bad news again. I apologize.
I continued to drive my pickup, and about one time out of ten the motor was not starting and I was waiting six minutes for cranking the engine again to get it started.
But I got poor or lost my judgement again and the engine was overheating. I even drove the pickup a little without water due to a radiator leak, probably because the water pump failed to do its job.
I have the radiator out. And I am also going to replace the thermostat, and, at this time the air duct assembly and the radiator shroud are removed, and the water pump is easier to access.
My question is if there is a way to check the water pump. The coolant in the reservoir is at normal level and it has been at normal level since before the engine started to overheat and I guess if I crank the engine the in taken air would not be filtered, but maybe I could get the motor started for a few seconds provided that his way I could find out if the water pump is working or not.
As always I can be told any information, advice or warning, and I appreciate all replies.
